It seems as though everyone has a smartphone now. You see them everywhere and they are simple to use, but they are incredibly complex actually and are full of advanced technology—a real miracle of modern engineering. The main chip in the latest Apple iPhone X, called the A11 Bionic, has more than 4.3 billion transistors—tiny electronic switches that allow it to do its job. All those transistors allow it to do all sorts of amazing things: browse the Internet, play videos, pinpoint your location, recognise faces or order pizza. Its built-in virtual assistant helps you organise your day. You can even use your smartphone to call up and talk to someone!

These miniaturised computers are amazing, but the best computer ever built lives not inside your smartphone but inside you, right between your ears. This computer doesn’t work using transistors, but with cells called neurons. The A11 Bionic might have 4.3 billion transistors, but the human brain has perhaps 100 billion neurons and 100 trillion connections between them! It is far more complex and powerful than any computers designed by mankind, and so, despite many years of research, no one completely understands how it works.

At its most fundamental level, an electronic computer is very good at remembering things and very fast at doing some basic maths, but that’s about it. On the other hand, our brains are so wonderful that we can look at someone and instantly know who they are. We can look at letters on a page and immediately know what they mean, whether it be poetry or a train timetable or the Bible. We can speak and listen to each other. We can joke, laugh and cry together. But say the same things to Siri, and she’ll think that all you said was “Egg freckles” or “Eat up Martha”.

But the brains that God gave us are particularly special, because they allow us to think. Forget artificial intelligence; this is real intelligence. We might use it to ponder the deep questions of life, like “What am I eating for dinner tonight?” or “What should I wear?”or “When is my assignment due?” But God has also given us the ability to think beyond the everyday: “Why am I here?”; “What is life really about?” Or at night to look up at the stars spread across the vast expanse of the universe and wonder, “Why does God bother with us?” God has put into us a desire to reach beyond the everyday and explore and discover the world He has made, and to look past the finite and into eternity. The intellectual capacity that God has given us needs to be exercised, and we must turn our thoughts towards Him.

And most significantly, all a computer can do is follow instructions—exactly so. They might not be the instructions you’ve given it, but unfortunately it doesn’t know any better, because it is following its manufacturer’s or programmer’s instructions. But God has given us all a mind that can make real choices. God has given us free will. He has given us the freedom to select between bad and good, and between good and better. What we choose and which way we go is always our own responsibility. We have to choose between going the right way and the wrong way. Thankfully, God has given us guidance for what we should choose through His Word, the Scriptures.

In Deuteronomy 30:19-20, Moses says “I have set before you life and death, blessing and cursing: therefore choose life, that both thou and thy seed may live: that thou mayest love the Lord thy God, and that thou mayest obey his voice, and that thou mayest cleave unto him: for he is thy life, and the length of thy days”.

It is our choice which way we go; no one else can make the choice for us. Let’s not get caught up in today’s technological world but look instead to the tomorrow of God’s eternity. God has offered us great riches; let’s therefore choose the path of life.
